The Amphenol 91276-401HLF is a single-position BERGSTIK® II unshrouded header — a board-to-board male pin that carries 5 A per circuit at 110 V. With one position loaded, this is the minimal footprint in the series: a single 0.100" (2.54 mm) pitch pin that mates with a matching BERGSTIK receptacle on another PCB.
The 110 V voltage rating is moderate; fine for signal-level and low-voltage DC power, but not for mains or high-voltage bus work. The 0.100" (2.54 mm) pitch is the standard BERGSTIK spacing, so this pin lands on the same grid as any other BERGSTIK header — useful if you need a single break-out pin on an existing footprint.
Unshrouded and push-pull fastening — no locking ramp, no polarization. The single pin can be inserted either way, which simplifies field wiring but means the connection relies entirely on the friction of the pin and receptacle. The through-hole solder termination with a 0.225" (5.72 mm) post length suits standard PCB thicknesses. This is a low-complexity part that feeds the line easily from a bag — no reel, no MSL concern, just a through-hole pin that wave-solders in place.
